A 28-year-old single mother who works as a server at a restaurant says she was denied her right to pump her breast milk while on the job. Kristen Joseph has worked at Hennessey's Tavern in Seal Beach for three years. She balances her job with caring for her six-month-old son, Wrigley. Joseph says that she usually takes a 10 minute break to pump her breast milk in the manager's office. But this past week, when she asked the on-duty manager for the keys to the office, she says she was told no.
